A Harry Potter Fanfic

What if, after defeating Lord Voldermort, Harry, Ron and Hermione went back to Hogwarts to finish their seventh year? What if the Dursley’s had a daughter who happened to have magic? What if she went to Hogwarts and fell in love with her cousin’s worst enemy? Can Harry, Ron and Hermione take any more drama?

@swimfreak24 it's a story. It's called being creative. She doesn't have to follow what the Harry Potter books say.
@PaigeDaniels I like the story so far! No errors as far as I can see. I think I'm going to love it ^-^
